WebApr 5, 2016 · A molecule is chiral when it doesn't exhibit any kind of symmetry. This particular molecule exhibits centre of inversion symmetry, i.e. it's symmetrical about a particular point. In this question that point is the midpoint of the bond joining the two substituted carbons. Chirality /kaɪˈrælɪtiː/ is a property of asymmetry important in several branches of science. The word chirality is derived from the Greek χειρ (kheir), "hand", a familiar chiral object. An object or a system is chiral if it is distinguishable from its mirror image; that is, it cannot be superimposed onto it. Conversely, a mirror image of an achiral obj…
